Abstract: An information processing device according to the present invention comprising: a management information storage means for storing management information; a reception means for receiving transmission data including management information from a predetermined network device; a management information update means for updating and storing the management information included in the transmission data into the management information storage means in a case that the management information included in the transmission data received from the predetermined network device is changed with respect to management information stored in the management information storage means; a transmission means for transmitting change management information that is information based on the changed management information, to still another network device, wherein the transmission means transmits the change management information to a network device specified based on information included in the transmission data received from the predetermi

Abstract: A network connection apparatus includes, a pair of line interface circuits which accommodates each transmission line provided to interface with the circuit-switched network, composes an active line and a standby line of the redundant configuration, and mutually converts data used in the circuit-switched network and a packet used in the packet-switched network; and a packet processing unit which interfaces with the packet-switched network and performs a sending and receiving process of the packet between the line interface circuit and the packet-switched network. The packet processing unit transmits the packet received only from the line interface circuit of the active line to the packet-switched network, and transmits the packet received from the packet-switched network to both of the line interface circuits of the active line and the standby line.

Abstract: The present invention provides a data transmitting apparatus capable of switching a plurality of switches and performing different data transmission processes to effectively transmit data. According to an exemplary aspect of the invention, a data transmitting apparatus 1 includes a plurality of switches 100-1 to 100-n (n is an arbitrary integer) that perform different data transmission processes, and uses the switches 100-1 to 100-n to transmit data. The data transmitting apparatus 1 is connected to interfaces 200-1 to 200-n including physical lines accommodated therein. The data transmitting apparatus 1 switches any one of the switches 100-1 to 100-n used for data transmission according to the type of physical lines in the interfaces 200-1 to 200-n.
